The Killer Whale is the largest member of the dolphin family and can be found in more parts of the world than any other cetacean. Killer Whales may be solitary or live in groups of 2 to more than 50. They generally cooperate during hunting and have even been known to prey on blue whales, the largest species on earth. This creature has it all, speed, power and strong special abilities of sonar pulse and sonic attack. Combine those with very high health and intimidating size, you have a fairly expensive creature. Keep its cost and research level low by combining it with lower ranked animals.
